Injection – Ignition
The ignition - injection system is
controlled by a single microprocessor
electronic control unit (ECU). This way,
engine performance and fuel
consumption are both optimized, the
former thanks to an improved car
drivability and the latter thanks to a
better engine operation with partial
loads.
Injection
– Bosch ME7.1.1 type
Ignition
– Static ignition
– Firing sequence: 1-8-6-2-7-3-4-5
